Abstract

Le procédé selon l'invention consiste à diviser (7) deux signaux de sortie (A1a et A1b) d'un ensemble microphone (1), qui sont des signaux acoustiques dépendant différemment de la direction d'incidence (ζ). Il consiste également à saturer (12) un produit du résultat (A7) de la division et d'un facteur de saturation (α), et à le soustraire d'une valeur de signal (A) pouvant être entrée. Le résultat de la soustraction est multiplié (13) par le signal de sortie respectif de l'ensemble microphone (1), qui forme le signal dénominateur pour la division (7). Une directivité souhaitée est produite en fonction du facteur de pondération (α) de la valeur de saturation (B) et en fonction de la valeur de soustraction (A), entre le signal de résultat (Sout) de la multiplication et la direction d'incidence (ζ) des signaux acoustiques arrivant sur l'ensemble microphone (1).
